Hi guys
i am sorry for this noob question
i am new to this form and mining system
i just want to ask is it worth to buy the avalon nano usb 3.6GH/s
i know this age is for Th/s now
but still is it profitable
At this point, it is not worthwhile if you are trying to make a ROI. If you can get one for dirt cheap, it may be useful to learn how things work and just get your feet wet.
Not at all. The Avalon Nano is (was) a very efficient miner and made around 3 cents a day a few months ago before the crazy difficulty rise. Nowadays the outdated avalon chip doesn't make profit anymore, and it's just a good idea for people who want an entry-level miner that doesn't eat up a ton of electricity. You can buy one if you like, but seriously for beginners a block erupter is a lot cheaper and has lots of mods available and also is very well documented.
A Block Erupter would achieve the same learning goal as leowonderful suggested for a lot cheaper if you plan on getting one on eBay or something.
